Nearly two feet in length in very good functioning condition this massive lock, likely German, has been beautifully restored without damaging it. 20" H x 10.75" W, key 8.5" L 

Very good with original finish this strong lock is still useable if I’m not mistaken. However I believe it would make a lovely decor piece in the home. You don’t come across these very often and in such amazing condition, especially considering their age.
